Title: Dc motor
Inventor: AKIYAMA TOSHINORI
IPC: H02K23/66
Filed: 1986-06-02
Abstract: PURPOSE:To keep the stable state of sliding, to prevent the generation of noises and to lengthen the life by laminating a sintered metal impregnated with oil on the surface on which segments in a commutator for a DC motor are slid with a brush. CONSTITUTION:Copper plates D for a plurality of electrodes 4b in a commutator 4 for a DC motor are monolithic-molded with a resin holder 4a. Sintered layers C in which the alloy powder of gold and silver is sintered and impregnated with oil are formed on the surfaces of the copper plates D. The mean particle size of the alloy powder is brought to 0.1mum, the thickness of the layer C is brought to 50mum, and aliphatic group oil having low viscosity is used as the impregnated oil. Accordingly, the stable state of sliding is maintained between the layers C and a brush, thus preventing the generation of noises, then resisting long-term use. The DC motor is suitable for a tape recorder.

Title: Temperature compensating type polarographic sensor
Inventor: OGURO TOSHIO
IPC: G01N33/493
Filed: 1995-04-28
Abstract: PURPOSE: To provide a polarographic sensor which has a temperature compensating function, and can output a stable signal even when the ambient temperature is fluctuated, and perform a highly precise polarographic analysis. CONSTITUTION: This sensor has a polarographic cell 12 having a working electrode 26 and a counter electrode 28; a potentiostat 14 for applying a prescribed voltage to the electrodes of the cell; and a current detecting resistor 48 for converting the current carried between the working electrode 26 and the counter electrode 28 into a voltage signal. The current detecting resistor 48 has a negative temperature coefficient, and is formed of, for example, a thermistor. Since the resistance value of the thermistor 48 reduces, when the ambient temperature rises, through the current carried between the working electrode 26 and counter electrode 28 of the cell, a sensor 10 outputs a stable voltage signal regardless of the temperature.

Title: Method for separating dot area
Inventor: OUCHI SATOSHI
IPC: H04N1/40
Filed: 1990-05-19
Abstract: PURPOSE:To separate a dot area from a non-dot area with high accuracy by increasing/decreasing a threshold level depending on the degree of possibility of a picture element of interest to be resident in a line drawing area. CONSTITUTION:The method consists of a white level/non white level picture element discrimination section 1, a dot peak picture element detection section 2, and a dot area detection section 3. A center picture element is detected as a notch or a dip picture element of a dot when a density level of the center picture element is a maximum or a minimum in comparison with other picture elements and a value corresponding to the notch or the dip of the dot is a threshold level TH or over by the specific calculation using the density level of the center picture element and the density level of the picture element in the relation of point symmetry with respect to the center picture element in a local area in 2-dimension based on a digital multi-value data of the picture. Moreover, the threshold level TH for criterion is increased or decreased depending on the degree of the possibility that the center picture element is resident in a line picture drawing area such as a character, that is, depending whether a which level area of a prescribed size or over exists the center picture element. Thus, the dot area separation with high accuracy is attained.

Title: Superconductive magnet
Inventor: NAKAO HIROYUKI
IPC: H01F6/04
Filed: 1991-05-31
Abstract: PURPOSE:To increase a rigidity of a heat shielding plate, to cool down the heat generated due to an overcurrent directly, and to reduce an increase of heat load of the entire superconductive magnet in operation by making the heat-shielding plate honey-comb structured and by allowing the cooling medium to flow inside the honey-comb construction. CONSTITUTION:A superconductive magnet is constituted of an inner vessel 2 to store a superconductive coil 1 cooled down by the medium such as liquid helium in, an outer vessel 3, a vacuum container, to house the inner vessel 2 in, a heat-shielding plate 4 located between the inner vessel 2 and the outer vessel 3, and other components. The superconductive coil generates a thrust, flotation force and guide force against a ground coil 5. The heat-shielding plate 4 is formed in such a shape as to surround the inner vessel 2 for reducing radiation heat coming into the inner vessel 2. For the heat-shielding plate 4, a honey-comb structured plate having a high rigidity is used. And, the cooling medium can be allowed to flow in the honey-comb construction. As for the honey-comb construction, a hexagonal honey-comb core 4b is used and a hole 4c is made as a path to allow the cooling medium to pass through. By this method, a high rigidity is obtained even at a part where restrictions are imposed on size such as a part of the magnet which faces the ground coil 5.

Filed: 1986-06-06
Abstract: PURPOSE:To easily observe an image by correcting a gradation emphasis processing amount in case of displaying each frame of a gradation emphasizing circuit by the variation of a luminance level of the image which has been detected. CONSTITUTION:The titled processor is provided with an image level detector 17 for inputting a video signal from a photographing means or a digital image data from an A/D converter 6 and detecting a luminance level of every frame, and by the variation of the luminance level of this detected image, a control part of a gradation emphasizing circuit 10 corrects a gradation emphasis processing amount in case of displaying each frame of its gradation emphasizing circuit 10.

Accordingly, it is unnecessary that an operator changes the gradation image by his manual operation, and its operability can be improved remarkably. Especially, in case of photographing plural sheets one after another and continuous photographing as a moving picture such as angiography, etc., it is possible to follow up a flow of an image automatically.

Abstract: PURPOSE:To provide a small-sized mounting apparatus operable at high speed and capable of of enlarging the types of components by arranging three different sucking nozzles, namely large-, medium- and small-diameter nozzles concentrically to provide a triple nozzle structure, such that the medium- and large-diameter nozzles can slide vertically to the small-diameter nozzles serving as the reference axis. CONSTITUTION:When a small-diameter nozzle 1 is used, both of medium-diameter nozzle 30 and large-diameter nozzle 22 are raised such that the tip end of the small- diameter nozzle is projected out. When the medium-diameter nozzle 30 is used, the medium-diameter nozzle 30 is lowered so as to be projected out over the tip end of the small-diameter nozzle 1 while the large-diameter nozzle 22 is kept in the raised position. When the large-diameter nozzle 22 is used, the large-diameter nozzle 22 is lowered so as to be projected out over the tip end of the middle-diameter nozzle 30. The medium- and large-diameter nozzles 30 and 22 are held stationarily in the raised or lowered position by using permanent magnets 25 and 32, and the mediumand large-diameter nozzles use the small-diameter nozzle 1 in common as a vacuum path. In this manner, the three different nozzles, namely the small-, medium- and large- diameter nozzles can be assembled in a compact size, suitably for providing a small- sized mounting apparatus operable at high speed.

Title: Still reproducing system for video signal reproducing device
Inventor: NAKASE HIDEO
IPC: G11B15/29
Filed: 1990-05-22
Abstract: PURPOSE:To excellently reproduce a still by making a tape travel a little after the traveling of the tape is stopped, locking a reel on a supply side thereafter, returning the tape to a regular stop position and relaxing the tension of the tape. CONSTITUTION:When the stop position of the tape is decided, a system controller 20 makes a capstan driving circuit 22 output a pulse-like driving voltage, for example, to a capstan motor 23 for a very short time. Then, a capstan 9 is turned a little and the magnetic tape 2 is moved forward (in a proceeding direction at the time of reproducing). When it is moved as long as prescribed length, a reel brake is turned on and a supply reel 3 is locked. Then, by reversely rotating the capstan 9, the tape 2 is moved backward (in the proceeding direction at the time of rewinding). Thus, the tension of the tape is lowered and an accident that the tape is damaged hardly occurs even when the still is continuously reproduced for a long time under such a state.
